              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Started out partly cloudy but clearing. Winds were from the east. Seeing was awful. Winds continued to increase, as well as humidity. Wind did not exceed safe limits, but humidity finally went too high around 00:00, and we closed. Humidity began to drop around 05:00 and we opened. Seeing had improved, now it was just bad, not awful. Clouds started rolling in, though. Nonetheless, we persisted.
